The perimeter of a rectangle is given by the formula 2(l+w)

The perimeter of a rectangle is given as 90 feet.

So the equation to represent this will be 2l\ +\ 2w\ =\ 90\rightarrow equation 1.

The length l is given as 5 feet less than 4 times the width.

The equation to represent this will be

l = 4w - 5 \rightarrow equation 2.
